Abstract: An authentication method can be performed in view of a pairing of a peripheral device to a companion device via a host device. The method includes initiating a pairing session and, in response to the initiating, receiving a first command by the host device. The first command comprises a first command code and a first encrypted payload to be exchanged between the peripheral device and the companion device via the host device. The first command code indicates to the host device to transfer the first command without decoding it.

Abstract: An authentication method is used in pairing a peripheral device to a companion device. The peripheral device sends a first identifier and a first value of a first counter to the companion device. The companion device verifies whether a pairing table stored in the companion device contains the first identifier. When the pairing table does not include the first identifier the companion device initiates a pairing session. When the pairing table includes the first identifier, the companion device compares the first value to a second value associated with the first identifier in the pairing table. In response to the first value being greater than the second value, the companion devices initiates a nominal session and in response to the first value being lower than or equal to the second value, execution of the method is stopped.
